This is the first prospective study of this size on chronic post-surgical pain which is a public health problem accounting for almost 15% of new consultations in specialist pain management institutions. Secondary objective: EDONIS also aims to identify pre-and peri-operative pain risk factors and to characterise its mechanisms with a focus on neuropathic factors. Eight types of conventional surgery were selected because (a) they are already known to induce persistent pain (thoracotomy, mastectomy, inguinal hernia repair), (b) they are frequently practised in France and chronic pain is an attribute (sternotomy, caesarean section, cholecystectomy, saphenectomy) or (c) surgery has a suspected risk of nerve injury (knee arthroscopy). There is also an associated ancillary genetic study. null France Individuals Patients population Male Female Young Adult (19 to 24 years) Adult (25 to 44 years) Middle Aged (45 to 64 years) Scheduled surgery identified as neuropathy-inducing Clinical data Participant-reported health data Biological data Health event/morbidity Health event/mortality Other Through organizations (health services or institutions schools businesses etc.) [1000-10000[ individuals Converting or copying information into a structured record Interview with the participant (including clinical) Observational Study Observational Study Cohort study 3330 Unknown Restricted access Data may be used by academic teams Access for collaboration with INSERM U792 team (Dr. Bouhassira) under the INSERM pain research network to improve diagnostic tools already developed by this team (DN4, QEDN) within the specific post-surgical framework.
